How do I stop my air conditioner from freezing up?

To sum up, here’s what you need to do to prevent the A/C from freezing:

  1. Have the refrigerant level checked.
  2. Change the filter monthly.
  3. Keep the supply vents open.
  4. Have the fan speed increased.
  5. Have the thermostat checked out.
  6. Inspect the condensate drain weekly.
  7. Make sure any window units you have are angled correctly.

What causes AC to keep freezing up?

The leading cause of a frozen HVAC system is a dirty air filter. The air filter cleans the air circulated into your home. As your AC system runs throughout the summer, the filter catches dirt, pollen, dust, and other allergens. This can restrict airflow and could lead the HVAC coils to freeze.

Can a dirty filter cause AC to freeze?

If the filter becomes clogged, it can cause malfunctions in the system. One of the consequences of a clogged filter is that it will cause the evaporator coil in the air conditioner to freeze over. This happens because the lack of warm air moving over the coil leaves the refrigerant inside the coil too cold.

How long does it take for AC coils to unfreeze?

It can take up to an 1 hour or 24 hours to unfreeze your air conditioner. It all depends on the extent of the ice buildup. As you’re waiting for the unit to thaw, you should keep an eye out for: An overflowing drain pan.

How do you unfreeze an outside AC unit?

Why does our a/C unit freeze up?

If your air conditioner is low on refrigerant, then your air conditioner can freeze up. This is due to lower pressure inside the system itself. This is because now there is less Freon in your system, but it is still being forced to expand the same amount – more expansion equals a cooler temperature.

Why your a/C freezes in the summer?

Cool summer nights can cause your AC to freeze Air conditioners are calibrated to operate within a certain set of optimum temperature thresholds. When nights in the summer time are colder than the optimum threshold can account for, it can throw an AC out of whack. Here is some more information on how to change your AC’s air filter.

What causes the a/C evaporator to freeze up?

If your unit is no longer cooling your home or is blowing hot air, your evaporator coil may be frozen. One of these common HVAC system malfunctions is likely the cause. Insufficient airflow is often responsible for an a/c unit freezing up. This means there is no air moving through the system.
